Tesla slates mysterious product unveiling for October 17

Here’s what we know: Tesla has scheduled an event for October 17 and it’s being called a “product unveiling.” Here’s what we don’t know: what the heck is going to be unveiled. International man of mystery (and, oh yeah, the company’s CEO) Elon Musk shared the news via Twitter, saying the unveil would be “unexpected by most.” In the absence of other details, the auto industry is having a field day speculating about what might happen next week.
